The Topology Optimization Design of Disc Brake Based on the OptiStruct

摘要: 以某客车盘式制动器为研究对象,在三维建模软件Pro-E中建立盘式制动器的三维模型,并在有限元分析软件OptiStruct中进行盘式制动器的模态分析,为了使制动盘和制动钳体不会由于共振而产生噪声,采用了变密度拓扑优化方法,建立了以质量最轻为优化目标,单元密度为变量,制动钳体的3阶模态为约束条件的拓扑优化。优化结果降低了制动钳体的3阶模态频率,并且给出了制动钳体的材料最优分布图,优化后的模态频率可以使制动钳体避免与制动盘产生共振而产生噪声。Abstract: Take one disc brake of a certain type of vehicle as study objection. Establishing the 3D model on Pro /Engineer software and finite element model on OptiStruct,furthermore,analyze the normal modes of disc brake. In order to avoid the noise carried out by the resonance between brake disc and the brake body,adopt the theory of variable density and establish an optimization that sets the minimum mass as objective,element density as variable,and the third modes of brake body as constraint. The analysis result provides an optimization that reduces the third normal modes,and involves the best distribution of material,with which the resonance can be avoided and the noise reduced largely.
